fix(db): use deterministic service IDs and add deduplication step

Browse Source 
Replace random uuid() for service IDs with pre-assigned deterministic
UUIDs (b0000001-0000-0000-0000-...) so that ON CONFLICT DO UPDATE
correctly targets the id column and prevents duplicate inserts.

Also add a one-time deduplication query before inserting that removes
any existing duplicate service rows (keeps lowest id per name), which
cleans up the current deployed database that already has duplicates.
